Abstract: Swing Motor Mounting Arrangement Abstract Swing motors employed on backhoes and like constructions vehicles are interconnected between a tractor frame and a mast frame to selectively rotate the mast frame relative to the tractor frame.  In addition to posing assembly and disassembly problems, conventional mounting arrangements for swing motors of this type oftentimes subject various spline connections, pins, and bearings to undue wear.  The swing motor mounting arrangement of this invention overcomes the above problems by providing a pair of first brackets for pivotally mounting a mast frame on a tractor frame and a pair of second brackets for securing opposite ends of a shaft of a swing motor to the mast frame.  A housing of the swing motor is connected to the tractor frame whereby pressurization of the motor will rotate the shaft relative to the housing to selectively swing the mast frame relative to the tractor frame.

Abstract: ABSTRACT OF THE DISCLOSURE      A grommet includes an eyelet and a washer both of rigid plastics which are matable together so as to be set in a fabric or sheet material.  The eyelet has a barrel having on one end thereof an annular locking flange projecting radially outwardly and an annular recess 16 adjacent to the locking flange 14.          The washer has an annular rib and a plurality of locking tongues projecting radially inwardly from the annular rib.          When the eyelet and the washer are coaxially combined within each other with the fabric or sheet material sandwiched there-between, the locking tongues are snapped over the locking flange into the annular recess.  The washer is now retained or trapped on the barrel by the locking flange against removal.  The advance in the art is in that the grommet can be easily attached to sheet material without the need for any attachment tool.          Furthermore, the grommet has parts snappable together so as to be set in sheet material, without being permanently bent or deformed.

Abstract: ABSTRACT            FUEL DELIVERY CONTROL ARRANGEMENT           A valving arrangement is disclosed for varying the quantity and timing of fuel injections of a jerk pump (10) associated with an internal combustion engine. The arrangement consists of a bypass valve (40) in com-munication with the injection chamber (22) of the jerk pump (10) which produces a controlled bypass of fuel rather than being delivered through the injector de-livery valve (42) to the engine cylinders.  The bypass valve (40) in turn is controlled by a solenoid-operated three-way pilot valve (883 which causes pressurizing or venting of an operating chamber (84) adjacent a by-pass valve operator piston (80).  The three-way pilot valve (88) in turn is controlled by the fuel system electronic controls (98) to control the timing and volume of fuel charge delivered by the jerk pump (10) in each injection cycle.

Abstract: 17                  49,092 ABSTRACT OF THE DISCLOSURE Composite  structure  for use as an HID device ballast component and which performs the dual functions of voltage transformation and provision of ballasting react-ance which can be controllably shifted in value.  A multi-leg magnetic structure has a primary winding carried on a first  leg  thereof and  an  output winding carried on a second leg thereof.   A control winding is carried on a third leg and a gap of predetermined dimensions is pro-vided in the magnetic path which includes the third leg. The magnetic core member and the windings carried thereon display  leakage  flux  paths of predetermined total per-meance.  A bilateral switch connects to the control wind-ing and is operable to be closed once each half cycle of normal lamp operation.  With the control winding closed, the counter mmf generated in the third leg decreases the inductive reactance of the structure by a predetermined amount,  with  the  inductive  reactance  of  the  structure essentially established by the permeance of the leakage paths.   With  the  control  winding  open,  the  inductive reactance of  the  structure  is  established both by the reactance of the wound third leg and the permeance of the leakage paths.  Thus, the effective ballasting inductive reactance can be controllable varied between two predeter-mined values in order to control the performance of the ballasted device and the composite structure also provides voltage transformation.

Abstract: A B S T R A C T        To enable molten metal to be transported through extended distance, for example from a holding furnace to a casting machine a pipeline is used which comprises a refractory liner which is externally heated by a heater, e.g. an electric heater, in response to temperature measurements made at spaced positions along the pipeline. The heater is surrounded by an outer layer of thermal insulation contained within an outer metal housing tube, which is cooled by coolant so as to match the expansion of the outer metal housing with the expansion of the refractory liner.  The pipeline is provided with means by which it can be tilted for emptying, e.g. at the end of a casting operation the contents of the pipeline may be run back into the holding furnace by lifting the outlet end of the pipeline.  The pipeline is composed of a series of pipe sections bolted end to end to form a relatively rigid structure.
